Mycotoxins; Aflatoxin M1 ; Brazil feeds; Dairy farms; Toxigenic fungi.Abstract
Brazil has regions located at the largest dairy production and milk derivate industry concentration, supplying the major consumer markets, represented by São Paulo, Rio de Janeiro and Belo
Horizonte Cities. The milk is the most important product of Brazilian agriculture, because it is
always presents in daily diet. The aim of this research was evaluating the occurrence of mycotoxins in the feed of dairy cattle and the occurrence of AFM1
in milk under field conditions in
farms from Rio de Janeiro State, Brazil. The results revealed that, total fungal counts was found
in 67% of feed samples which exceeded the recommended limit recommended (1×104 UFC.g-1)
and the incidence of AFM1
in all milk samples was 26.7% at concentrations ranging from
0.010 to 1.500 μg.L-1. The study revealed toxigenic fungi and their mycotoxins were present in
feed intended for bovine feeding in Rio de Janeiro farms. Evaluations of mycotoxin levels are
important to provide information so that the assessments of risk for animal feed and livestock
environment can be done.
